RefControl FLUX.2 Klein Reference Depth is an image editing workflow built around two inputs. The reference image tells the model what identity, clothing, style, or object details to preserve. The depth map tells it what pose, structure, and composition to follow.
That makes it more targeted than a normal image prompt. For example, you can start with a character portrait, provide a second image as the pose guide, and ask for a new scene where the character keeps a recognizable look instead of being regenerated from scratch. The Space can also make a relative depth map from a normal photo, so you do not need to prepare one before the first test.
